Hello, I'm pregnant at 20 weeks and am treating bronchitis. I've already taken antibiotics and cough tablets, and do two inhalations daily. But the wheezing with dry cough doesn't go away. I'm exhausted, what should I do? After inhalation, it seems like I feel better for an hour, then it starts wheezing again. Even my therapist doesn't know what to prescribe me anymore((I don't even know what can help... )
